Commonly used anchor chains are composed of many steel links, which are divided into cast steel anchor chains, flash welded anchor chains, and forged anchor chains according to the manufacturing method, and divided into geared chains and non-geared chains according to the link structure. The anchor chain can be composed of several "sections", which are connected by links or shackles. The strength of the anchor chain is relatively high, and its deformation under the action of external force is negligible compared with the displacement of water flow, and there is no active energy consumption, which is similar to a rigid connection.

detailed description:

See attached picture:

A cage mooring anchor chain adaptable to high-frequency oscillation and impact loads, including an ordinary anchor chain 22 and an elastic cable 21, the elastic cable 21 is assembled from a pull rod, two springs, a barrel, and a bottom sealing plate, and is subjected to mooring force When one of the two springs is subjected to tension and the other is under pressure, the elastic cable 21 can undergo a large elastic displacement, and the anchor chain system of the cage assembled by connecting the anchor chain 22 with a plurality of elastic cables 21 end to end has a dynamic buffer function. , which is beneficial to improving the safety of cages or anchoring foundations.

The bottom sealing plate 4 of the elastic cable 21 is a circular steel plate, which is evenly provided with connection holes 1 (bolt holes) 5 around, and a fixed rod 2 is provided at the center of one side of the circular steel plate, and a mooring rod is provided at the end of the fixed rod 2. Ring one 1, four triangular reinforcing ribs one 3 are uniformly arranged at the junction of the fixed rod 2 and the bottom sealing plate 4, and the other side center of the circular steel plate is provided with an earring one 6. The mooring ring 1, the fixing rod 2, the reinforcing rib-3, the bottom sealing plate 4, and the earring-6 are connected as a whole by welding.

One end of the pull rod 8 of the elastic cable 21 is provided with a mooring ring 7, and the other end of the pull rod 8 is provided with a circular supporting plate 10, and four triangular reinforcing ribs are evenly provided at the intersection of the pull rod 8 and the circular supporting plate 10 Two 9, the center of the other side of the circular supporting plate 10 is provided with an earring two 11. The mooring ring 7, the pull rod 8, the rib two 9, the circular supporting plate 10, and the earring two 11 are connected as a whole by welding.

The barrel body 13 of the elastic cable 21 is a steel hollow cylinder with a top plate, the central axis of the top plate is provided with a reserved hole 12, and the side of the hollow cylinder is symmetrically and evenly provided with a plurality of elongated hollow holes 14. A strip-shaped hollow hole 14 makes the weight of the barrel body 13 less, and the amount of steel used is less, while the strength of the remaining solid parts of the barrel body 13 meets the needs of various working conditions. The bottom of the hollow cylinder is provided with an outwardly protruding annular outer edge plate 15, and the outer edge plate 15 is uniformly provided with two connection holes 16.

Connecting hole one (bolt hole) 5 on the bottom sealing plate 4 and connecting hole two 16 on the staving 13, both hole size, position, quantity are identical, can be fixedly connected both by bolt 19.

The diameter of the circular supporting plate 10 on the inner pull rod of the elastic cord 21 is slightly smaller than the inner diameter of the barrel body 13 . The extension spring 17 and the compression spring 18 of the elastic cable 21 have a diameter slightly smaller than the diameter of the circular supporting plate 10; .

One end of the extension spring 17 is fixed on the earring two 11 at the bottom of the circular supporting plate 10, and the other end is fixed on the earring one 6 on one side of the bottom sealing plate; It can freely move up and down inside the barrel body 13 along with the movement of the circular supporting plate 10 .

The compression spring 18 is set on the pull rod 8, and the circular support plate 10 can cover and support the compression spring 18. The circular support plate 10 and the compression spring 18 are placed inside the barrel body 13, and the mooring ring 7 on the pull rod 8 passes through The reserved hole 12 of the barrel body 13 is placed outside. The circular supporting plate 10 connected with the pull rod 8 and the stage clip 18 can freely move up and down inside the staving 13 .

In fact, the size and material parameters of the extension spring 17 and the extension spring 18 are exactly the same, but under the action of the mooring force, the spring 17 is stretched and elastically deformed under the tension, while the extension spring 18 is compressed and elastically deformed under the pressure. .

Both the extension spring 17 and the extension spring 18 are high-strength springs, which can undergo relatively large elastic deformation and can withstand relatively large tension and pressure. The maximum elastic deformation length of the two springs is the maximum elastic expansion and contraction of one elastic cable 21 . When the tension becomes smaller, the elastic cable 21 can gradually recover from the maximum elastic deformation length to the original length.

The mooring rings 7 and the mooring rings 1 at the two ends of the plurality of elastic cables 21 are connected to common anchor chains through fasteners to form a new anchor chain system capable of large elastic deformation. The ordinary anchor chain here refers to the anchor chain connected by many steel links. Suppose the maximum elastic deformation length of an elastic cable 21 is , if n elastic cables 21 are used in an anchor chain system, the cumulative maximum elastic deformation of the anchor chain system is . When subjected to strong wind and waves, the anchor chain undergoes elastic deformation It will inevitably absorb and consume a large amount of wind and wave impact energy, so that the peak clipping of the wind and wave load on the cage and the mooring foundation becomes smaller and lags behind, which is beneficial to the safety of the cage and the mooring foundation. The traditional steel anchor chain cannot be deformed, and the large wind and wave load is directly transmitted to the cage and the mooring foundation in equal amounts, which poses a greater threat to the safety of the cage and the mooring foundation.

During the process of the maximum elastic deformation length of the elastic cable 21, part of the impact energy of the wind and waves has been converted into elastic energy of the spring and stored in the spring. When the wind and waves are small, the spring gradually restores deformation and releases the stored elastic energy, thereby having a power buffer function.

Each part of the elastic cable 21 is steel or iron, and the strength of the assembled parts and welds should be able to bear the mooring force transmitted by the anchor chain under the action of various random wind and waves without buckling and failure.

The number of elastic cables 21 required by the anchor chain system is comprehensively determined according to the size of the wind and waves, the length of the anchor chain, and the mooring method.

Elastic cables 21 can be made into standard parts, and a certain amount of elastic cables 21 are connected in common anchor chains as required to form a cage anchor chain system with energy dissipation. In particular, after each storm, the integrity of the anchor chain system should be checked in time, and the damaged elastic cables 21 should be replaced to maintain the effectiveness and safety of the anchor chain system.

The arrangement of the elastic cords 21 during use can be flexible and diverse, such as a plurality of elastic cords 21 connected to each other to form a "series" pattern, or a plurality of elastic cords 21 to be connected in parallel to each other to form a "parallel" pattern, which is an anchor The chain system provides sufficient strength and security.

One end of the utility model is connected to the mooring foundation 20 when it is working, and the other end is connected to the net box 23.

The utility model is not limited to the above-mentioned specific embodiments. According to the above content, according to the common technical knowledge and conventional means in this field, without departing from the above-mentioned basic technical idea of the utility model, the utility model can also be made into other various forms. The equivalent modifications, replacements or alterations all fall within the protection scope of the present utility model.
